The speakers are interesting to listen to IMO. They're the 1st sealed box units I've ever owned and listened to in detail. One tweeter was working on arrival which required a lorra lorra work to get going, the 'crossover' is mounted on the rear terminal panel and the components are point to point wired and glued to the panel! Yucky, dry joint city but rectified (in the non diodular sense) however the tweeter still wouldn't work. Very carefully dismantling the whole thing (splitting the coil from the hoooooge magnet assembly was fun I can tell ya)I found a break in the coil at the under some tape at tag board end, it looks like some corrosion had set in on the bared copper wire where the coil joins the outside world. Whahey, a successful repair so I reassembled and we've been listening to them this evening. They're OK, work well in the Conservatory on the end of the little Class D Pi amp.
However (dot dot dot). the surround of one of the Mid/Bass drivers has come slightly unglued over the years of storage up in the loft. On very bass-heavy music I can feel air (and music!) escaping via the loose section, not ideal. The surrounds are a rubbery sort of material and look like they were original fixed with a circular bit of double sided tape.
Whats a known good way of fixing the problem?
